As the guy who wrote the SMTC stuff, I'd recommend picking up something newer. Ralf has merged some of the subsequent improvements and fixes into 2.6.18, but not the patches that I made last year to allow tickless support, which is actually a very, very good thing to have for SMTC. That support was initially available in 2.6.24, but subsequently got broken by some changes to control register manipulation APIs that I identified and fixed a few months ago. Ralf back-merged them into several recent baselines, but I'm not sure which ones. 2.6.29-stable seems to have all the right patches applied for SMTC, but of course I can't tell whether there would be other issues for your platform.

Hi List,

I have got a reference board with mips 34k core SOC.I am planning to enable smtc/smp support . The reference kernel I am having is linux-2.6.18 which is in uniprocessor mode.

Could any of you suggest me in which way i have to proceed?. Does it make sense to continue using 2.6.18 or port newer kernel version ( which might be having better SMTC/SMP support)?
Thanks
An
